I have bought a residential site 7 years back near Bangalore Rural district of Karnataka. It is developed on a property belongs to SC/ST which ancestral property for the original owner. We have documents from 2000-2001 that shows this is a ancestral property. This property developed by a Developer based on GPA given to him from the original owner of the property. GPA holder (Developer) sold the sites to us in 2016. Do you see any legal issue in the purchase of this DC converted site?
